a city of Shirvan in Persia, and the best haven in the Caspian sea. It is defended by a double wall, as also by a ditch and redoubts, made by the Ruffians when they were masters of the place. It had a sumptuous castle, but it is reduced to a ruinous state by the Ruffians. Formerly many merchants resided here, and carried on a considerable traffic in raw silk; but that commerce is now given up. All the country round is much impregnated with sulphur, which renders the water very unpleasant. The neighbourhood of this city supplies the countries adjacent with naphtha, brimstone, and rock salt; and is the only place thereabouts which produces saffron. Round Bachu are several very steep craggy mountains, on which are strong watch-towers. E. Long. 49. 5. N. Lat. 40. 0.
